In a 'dragon sacrifice fanfic', the main characters could vary greatly. There might be a young hero or heroine who is forced to take part in the dragon sacrifice for the sake of their village or kingdom. There could also be an evil sorcerer who is orchestrating the sacrifice for his own dark purposes. And of course, there could be a group of adventurers who are trying to stop the sacrifice, thinking that it's an immoral or dangerous act. The dragon, if it has some level of sentience, could also be considered a main character, fighting for its own survival.
It really depends on the specific fanfic. However, often you might find classic WoW classes as main characters. For example, a paladin could be a main character, as they are often associated with self - sacrifice in the WoW lore. They might sacrifice their own health to heal their comrades or sacrifice their own safety to protect the weak. Another possibility is a rogue. A rogue might sacrifice their anonymity, which is very precious to them, to expose a conspiracy within the game world.
The main character is most likely the last dragon itself. But there could also be other important characters like a brave knight who tries to befriend the dragon, or a wizard who has some connection to the dragon's past.
In 'the dragon and the rose fanfic', aside from the dragon and the rose, there could be other characters too. There might be a wizard or a fairy who has some sort of relationship with either the dragon or the rose. For example, a wizard might be trying to control the dragon's actions regarding the rose, or a fairy could be the one who planted the rose in the first place and has a connection to it.
I'm not sure specifically as it depends on the fanfic. But it could have a brave knight who is not afraid of the ice dragon at first sight. He might be on a quest related to the dragon.
